Implication

Clinical trial demonstrates that dexmedetomidine infusion significantly reduces shivering during spinal anesthesia, indicating effective perioperative prevention without major adverse events.

Key Points

To evaluate the efficacy and safety of dexmedetomidine infusion in preventing shivering among patients undergoing minor surgical procedures under spinal anesthesia.
Enrolled 60 ASA I or II patients aged 18–50 years undergoing elective minor operations with hyperbaric bupivacaine spinal anesthesia.
Administered either saline control (group C, n = 30) or dexmedetomidine (group D, n = 30) perioperatively.
Evaluated motor block with the Modified Bromage Scale, while shivering incidence and intensity were monitored by a blinded observer after subarachnoid drug injection.
Shivering occurred in 3 of 30 patients (10%) in the dexmedetomidine group compared to 17 of 30 (56.7%) in the control group (p = 0.001), with significantly reduced shivering intensity (p = 0.001).
Hypothermia was observed in 21 patients (70%) in the dexmedetomidine group versus 20 patients (66.7%) in the control group (p = 0.781).
Median time to shivering onset was 10 minutes (range: 5–15) in the dexmedetomidine group and 15 minutes (range: 5–45) in the control group (p = 0.207).
